Summary Overall microbial levels in the water system of a turbot farm were similar to those found in regular sea‐water. At the end of an incubation period, however, the numbers of colony‐forming units (CFU) in Artemiu cultures and turbot eg incubation jars were up to four orders of magnitude...
Summary Gonadal maturation, rematuration, and spawning of nine‐ (1982 stock) and ten‐year‐old (1981 stock) milkfish reared in 150 and 200 m3 concrete tanks were observed in 1990 and 1991. From 23 September to 9 November 1990, the 1981 stock spawned 15 times with an average daily collection of...
Summary Variability in length‐at‐age of marine species of fish was studied using age and growth data and population‐specific life history and environmental parameters for 168 species in 50 families (458 records). The shapes of distributions, the magnitude of variability, the patterns of...
Summary The relationshis among carcass weight, acid‐base‐balance of the blood as an indicator for metabolic load susceptibility, meat quality parameters, and body Composition were investigated in rainbow trout. Examinations were carried out in two replicates using a total of 300 trout from a...
Summary Hatche and wild sea bass (Dicentrarchus labrax) fry were transferred from sea water to low salinities and freshwater (FW) usiny three different operational protocols: 1) direct exposure to ow salimues and FW (LC 50 test, ST 50 test); 2) quick acclimation to FW (48h); 3) slow acclimation...
Summary Screening an Atlantic salmon (Salmo salar L.) salmon kidney cDNA library with total cDNA led to the isolation of a clone which hybridised strongly to both salmon kidney and spleen total cDNA probes. Analysis of the sequence identified the cDNA as the gene coding for subunit II of...
Summary Observations made over a three‐year period at the Fish Diseases Laboratory of the African Regional Aquaculture Centre (ARAC), Nigeria, revealed the gradual emergence of a new, highly infectious septicaemic condition in some widely cultivated freshwater fish species. The broad host range...
